ABSTRACT:
Disclosed are a variety of processes for the purification of saline minerals and in particular, trona. Some of the processes include a combination wet and dry recovery process which results in high recovery and purification at relatively low cost. The dry separation methods can include density separation, magnetic separation and electrostatic separation. Other processes include a modified slush process for the purification of calcined trona (sodium carbonate) by the introduction of anhydrous sodium carbonate into a saturated brine solution and subsequent separation of insoluble impurities.
